If you've been dying to try out the one-number-to-rule-them-all phone service GrandCentral, but have been stymied by their move to a closed, invite-only beta following Google's acquisition of the service, you'll be glad to know that GrandCentral has opened up to users of Google's Blogger. If you're still undecided about whether or not GrandCentral is for you, check out our extensive review and gallery of GrandCentral. If you've been a user of GrandCentral since we first posted about it, let's hear how you're liking it in the comments. Thanks Jason!
